You are using the deprecated option "installed". Only installed packages are shown by default now. The --all option can be used to show all packages.

I need to setup a PHP 5.6 using composer install .

But I get mcrypt extension error:

$ composer install

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update
Generating autoload files
> php artisan clear-compiled
Mcrypt PHP extension required.
Script php artisan clear-compiled handling the post-install-cmd event returned with error code 1

I have tried also:

$ /usr/bin/php5.6 /usr/local/bin/composer install

and

$ alias composer="/usr/bin/php5.6 /usr/local/bin/composer"
$ composer install

But always with same error.

Any idea about to force composer to use PHP 5.6?

Thanks!

Answer 1

The problem is not about composer, is about php artisan clear-compiled and php artisan optimize configured in post-install-cmd composer.json event.

This commands are executed with native php-cli version.
